Upgrading from any version prior to 8.5/8.6 is simply saving you money now by getting the 10 upgrade for free. Essentially, you are upgrading to 10 for the price of upgrading to 8.6.
For those of you that are at 8.5 or 8.6, they have not forgotten about you and something will be offered once 10 is released in Sept.
Upgrading is not for everyone, as you said Visual800. If it works and you do not need any improvement, stay where you are. I am of the belief that staying up to date pays in the long-run. Investing in the right technology can improve any
sign/print/engraving shop out there... efficiency, added features, faster output, etc.
I have been told that the Mac version will be released with the PC version. I hope this is accurate and comes to fruition.
If you bought an upgrade to 8.6 in June, give me a call and I will be happy to "go to bat for you". No promises, but I will pull out the bat and try.
